Hi,
I am using:
Java 11
Ubuntu 20.04.2
Hadoop 3.3.1
Zookeeper 3.7.0
Accumulo 2.0.1
I followed the instructions here:
https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/SingleCluster.html
and edited etc/hadoop/hadoop-env.sh, etc/hadoop/core-site.xml, etc/hadoop/hdfs-site.xml accordingly.
'ssh localhost' works without a passphrase.
Then I started Zookeper, start-dfs.sh and start-yarn.sh:
christine@centauri:~$ ./zookeeper-3.4.9/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /home/christine/zookeeper-3.4.9/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
christine@centauri:~$ ./hadoop-3.3.1/sbin/start-dfs.sh
Starting namenodes on [localhost]
Starting datanodes
Starting secondary namenodes [centauri]
centauri: Warning: Permanently added 'centauri,2003:d4:771c:3b00:7223:40a1:4c07:7c7b' (ECDSA) to the list of known hosts.

BUT
when running 'accumulo init' I get this Error:

I am not able to find the mistake. I found similar questions on Stackoverflow, but none of them solved my problem.
Thanks in advance for any idea.
